A fundamental force of nature, gravity shapes our entire universe. It sculpts galaxies and warps space and time. But gravity’s strange powers also affect our daily lives in the most unexpected ways. This is a story with surprises in store for Jim himself. In telling the story of gravity, his own understanding of the nature of reality comes to be challenged.

Forget the Big Bang. The real moment of creation was the moment of first light, the moment the first stars were born. Horizon tells the scientific version of the story of Genesis.

The oceans define the earth. They are crucial to life and we used to think that they were unique to our blue planet. But we were wrong.

Until very recently the whole idea of the multiverse was dismissed as fantasy. Horizon asks whether multiple universes exist and, if so, which one we are actually in.

Documentary following researchers as they try to take the first-ever picture of a black hole. They must travel the globe to build a revolutionary telescope that spans planet Earth.

Diamond rain, supersized volcanoes, exploding oceans - and we have a front row seat for it all. Professor Brian Cox reveals the strange worlds visible to us as never before.

Professor Brian Cox journeys to the volcano worlds of the solar system and explore alien landscapes bursting with fire and ice. There are planets and moons covered in volcanoes, with eruptions so violent they reach into space. Understanding what makes these worlds active is critical in the search for life beyond Earth.

He visits some of its least explored regions and finds out what lies beyond the reach of even the most powerful telescopes. The solar system is not just a few worlds orbiting close to the Sun - it’s an enormous structure that stretches halfway to the nearest star.

Professor Brian Cox explores the solar system’s wildest weather, encountering powerful lightning, strange metallic frosts and monsoon rains on a moon a billion kilometres from Earth.

Professor Brian Cox explores the solar system’s ice giants, frozen moons and worlds where ice behaves in unimaginable ways.

Professor Brian Cox explores the solar system’s misfits and oddballs, and investigates the forces that sculpted the bizarre features on these strange worlds.

Prof Jim Al-Khalili tackles the biggest subject of all, the universe, through a series of critical observations and experiments that revolutionised our understanding of our world.

In this second part, Professor Jim Al-Khalili carries us into the distant future to try to discover how the universe will end - with a bang or a whimper?
